The reasoning is that it is a tricky situation, which may not be handled
everywhere in code base, e.g., depending on the regexp used. As
a consequence you're in /terra incognita/ anytime you use such
constructs.

FWIW, I don't even see empty headlines useful anywhere. You can, for
example, use \nbsp{} or some such to hide a headline. But IMO, it looks
weird in overview display and is totally uninformative.

Possible. The fact that we're having this discussion means we should
probably choose one option, write it down in Org syntax, then deal with
the bugs. Which option is open for debate. I am not married to any of
them.
